The table shows the temperatures in
some cities in a day. Find the city that has the closest
temperature to that of city A.
And then we’ve got a range of
different cities with different temperatures. So A is twenty-seven degrees
Celsius, B is twenty-five degrees Celsius, C is thirty-eight degrees Celsius, D is
thirty-two degrees Celsius, and E is twenty-three degrees Celsius.
Right, let’s picture our
thermometer and I’m just gonna map the temperatures onto that thermometer. So A is twenty-seven degrees
Celsius, B is twenty-five, C is thirty-eight, D is thirty-two, and E is
twenty-three.
Now the question asked us to find
the city that has the closest temperature to that of city A. Now I’d have to step up five
degrees Celsius to get up to D. But I’d only have to step down two
degrees Celsius to get down to B. So the difference in temperature
between cities A and D is five degrees Celsius and the difference in temperature
between cities A and B is only two degrees Celsius. So city B has got the closest
temperature to city A. Now you didn’t have to draw out the
scale; you could have just done the calculations by hand and done a bit of
subtraction or addition. But our answer either way is city B
has the closest temperature to city A.
